I have a datagrid that when an item is clicked, the complete
data for that item populates a form where the user can edit it. I
want to make it so if the user changes anything on the form, then
clicks on another item in the datagrid, a warning comes up letting
them know that they have changed the data and giving them a chance
to save it before they change to another item.
is this possible? I can keep track of when they change data,
and I can pop up a warning when they change the selected row, but
how can I prevent it from happening in the first place until they
are given a chance to save the data?
